Seriously. I've wound up deleting and reposting threads in the past because of a minor typo I caught immediately after clicking submit. There should be a window of a few minutes to ninja edit titles just like there is with body text, with some way of editing titles afterwards with an "edited" notice. Either allowing the mods to do it for cases like this, where the rules require some piece of punctuation or a date or what have you, or just allowing the users to do it wholesale.
